Snap #69: A car that runs on solar energy

On the Snap #69 show on July 16, 2022:

• A Chinese team has just presented the Tianjin, a car that works with solar energy. At the moment, this is just a prototype, but the latter shows promise. In fact, the machine is equipped with level “4 plus” autonomous driving. It can travel about 75 km per day at 80 km/h. Equipped with solar panels, the Tianjin also has a converter to recharge it electrically if necessary.

• The Dryad sensor has been designed to detect a fire in less than 60 minutes. This little box also measures temperature, humidity, and air pressure. The Dryad is equipped with a GPS to obtain the precise geographical position of a fire source. It is solar powered and will not require a battery change for 10-15 years. Such fire detection technology is both a time saver and a way to reduce the risk of accidents.

• On December 18, the James Webb Space Telescope replaced Hubble. Located 1.5 million kilometers from Earth, it can observe celestial objects in both infrared and visible light. This week we received the first images produced by the latter. One of them constitutes the “austral ring” nebula. We also see a galaxy. Images as impressive as they are important for scientific research.

• Seedze is a wellness kit that relieves pain and calms users’ anxiety and fatigue. According to its designer, it could do it in less than 5 seconds. This small device combines aromatherapy with infrared radiation therapy, including thermal therapy. It is possible to choose the Seedze temperature according to your pain, since there are three different models.

• Qoola is a great ally when it’s hot. Indeed, it is a mini portable air conditioner to wear around your neck. This ionizing air purifier also removes micro dust such as pollen. In summer it becomes a small hot water bottle, since it has 4 temperature modes that vary from 15 to 45 degrees.
